Many drivers have experienced problems with their car alarms. You may find it annoying if your alarm goes off at night or in the most peaceful time of the day. You might think your car has been stolen or damaged. However, in some cases, this may not be the case. Continue reading to learn more about the cause and how to fix it.
How does the car alarm system work?
You need to understand the basics of car alarms before you can start investigating why your car alarm sounds unexpectedly. Although there are many types of car alarm systems available, including retrofitted, fabricated and old, most operate with the same logic. You may need to use a diagnostic tool to check the codes in your vehicle’s factory alarm system. You can then diagnose the problem and fix it more quickly.
Nearly all car alarm systems can be connected to trunk and door sensors. It deactivates the alarm when you unlock your car using the remote. The alarm will sound to notify the driver if the alarm system has been activated and the door is opened (unlock), but it won’t deactivate if the trunk or door is opened.
Alarm systems may use impact/shock sensors. Shock sensors detect vibrations and shocks. This alarm system helps to prevent theft. When someone crashes into your car, or attempts to break in through the windows, the alarm goes off. This is crucial because burglars can open windows and get into your vehicle without using shock sensors. They must open the door to activate the alarm. The shock sensors add an extra layer to your vehicle’s protection. When the thief attempts unlock your vehicle, the alarm will go off and the thief is taken hostage.
Random Car Alarm Causes
Your car alarm can sound randomly without any strain for many reasons. These are the top causes.
1. Dead Battery
While it might not make sense at first, a dead battery or low-charged car battery can lead to many unusual problems. It is very common for an alarm to be triggered by a dead battery or another electrical problem. If the battery level drops, the alarm will sound to warn you and cause the engine to stop.
Check the battery if the alarm sounds at random times, or if the vehicle is having trouble starting. You should replace your battery if the voltage drops below 12.6 volts.
2. Defective Control
Faulty remotes are one of the leading causes for car alarms to go off continuously. Remotes are used to activate the alarm by hand. It can be set up at will and trigger the alarm when there is an issue. A faulty remote will send a false alarm and the car alarm will be activated.
You can try changing the battery to see if it helps. You can also reset some controls. For reset instructions, check your vehicle’s manual.
3. Sensors that are dirty or damaged
To alert you to a problem, your car alarm uses several sensors. Your car alarm will be deactivated or armed if some of the sensors fail to work properly. Common causes of car alarm malfunction are damaged or dirty door, trunk or hood sensors.
4. Cable issues
The alarm system for your car uses electricity and the wires that carry it are connected to it. If all is well, the alarm will not sound. However, if wires are shorted or damaged or incorrectly connected, the alarm will continue to sound.
5. Extremely sensitive Shock/Impact Sensors
These sensors can trigger an alarm at varying levels of sensitivity if they are fitted to a car alarm with a shock sensor. The alarm can go off if pets, dogs, or a ball accidentally hits the hood. An auto electrician can also adjust shock sensors that are extremely sensitive.
6. Defective Control Unit
Alarm systems all have a control unit that transmits information to the sensors. The control unit can fail in rare circumstances. You can test the voltage to your controller after you have tested all the wiring and sensors.
7. Faulty Assembly
You may have faulty installations if you retrofit an alarm system to your car. An incorrect connection or improper installation of sensors can cause the alarm to sound, or even stop working altogether. A multimeter can be used to verify that all wires are receiving power.
How to disable a car alarm
You may wonder why the car alarm is ringing so often. Without software manipulation, it is almost impossible to deactivate a factory alarm. If you have an auto-alarm fitted to your car, there are several ways you can disable it.
These options are usually sufficient to disable a beeping alarm. However, if it doesn’t go off, there are other options.
1. Start the Car
The car alarm should not go off if there is nothing wrong. This is how the control module can detect who is operating the vehicle. It may not work with older vehicles.
2. Locking and closing the car
Sometimes all that is required to reset your alarm system and turn off the alarm is to lock the car. Most car alarms will not work if you don’t lock or unlock it.
3. The Fuse can be removed
This is the best way to go if your first two attempts failed. The circuit protects your car alarm system. If you remove the fuse, it will turn off the alarm. No power, no alarm!
Modern cars with factory alarm systems will have the fuse integrated into the central electronic mode. This means that this method won’t work.
4. Remove the Battery
If you cannot locate the fuse or need to turn off your alarm, the last option is to disconnect the battery. If you disconnect the battery, the vehicle will stop starting. This is a last resort option, but it will work until you can find an auto electrician.
If your car alarm is sounding constantly and suddenly, you should immediately fix it. This will cause inconvenience to others. The car battery is also affected by the constant alarm sounding.
